Proton Pump Inhibitors (PPIs)

Proton pump inhibitors (PPIs) treat certain gastrointestinal disorders. They reduce the amount of acid in the stomach. PPI drugs are available over the counter (OTC) and in prescription form. PPIs can cause life-threatening side effects. There are thousands of lawsuits over proton pump inhibitors.

Suffering from serious side effects after taking a PPI?

If you took a Proton Pump Inhibitor (PPI) like Nexium or Prilosec and suffered kidney damage or injuries, you may be entitled to compensation.

Proton pump inhibitors (PPIs) are among the most commonly used drugs in the world. About 15 million people in the U.S. use PPIs every year.

People take PPI drugs to treat gastrointestinal symptoms like frequent heartburn. But studies suggest as many as 70 percent of people taking PPIs get no benefit from them.

Some people may be able to try alternatives to PPIs like lifestyle changes or H2 blockers.

For those who take PPI drugs long-term, side effects can be serious or even deadly. Proton pump inhibitor side effects include kidney problems, bone fractures and heart attacks.

Thousands of people have filed PPI lawsuits. They claim PPIs caused kidney failure and other injuries.

What Is a Proton Pump Inhibitor and How Does It Work?

Proton pump inhibitors are powerful acid-reducing drugs. PPI drugs target proton pumps in the stomach. These tiny pumps cause a chemical reaction that produces stomach acid. PPIs limit the amount of acid the pumps produce.

Diagram showing how PPIs reduce acid
PPIs shut down pumps in the stomach that produce excess acid.

The body absorbs proton pump inhibitors into the bloodstream. From there, they send signals to the acid-forming cells in the stomach lining. These tell the cells to reduce the amount of acid they produce.

List of PPI Brand Names vs. Generics Available in the U.S.

There are eight brand name proton pump inhibitors in the U.S.

All PPI drugs are available in prescription strength. Nexium, Prilosec and Prevacid come in over-the-counter (OTC) versions, too.

PPI brands except Dexilant and Vimovo can be found in generic forms. Pediatric versions are available for Prilosec, Nexium, Prevacid, Zegrid and AcipHex.

Fact
Nexium is the biggest selling PPI and one of the best-selling drugs in history. AstraZeneca reported sales of $72.5 billion for Nexium between 1992 and 2017.
Proton Pump Inhibitors List: Available Prescription, OTC & Generic PPIs
  • Omeprazole (Prilosec, Prilosec OTC, Zegerid)
  • Esomeprazole (Nexium, Nexium 24HR)
  • Lansoprazole (Prevacid, Prevacid 24HR)
  • Dexlansoprazole (Dexilant)
  • Pantoprazole (Protonix)
  • Rabeprazole (AcipHex)
  • Esomeprazole/ Naproxen (Vimovo)

What Are PPIs Used to Treat?

Prescription proton pump inhibitors treat serious, gastric acid related conditions. Over-the-counter PPIs treat frequent heartburn.

Prescription PPIs Treat
Gastroesophageal reflux disease (GERD)
A chronic digestive disorder caused when stomach acid flows back into the esophagus
Helicobacter pylori (H. pylori)
A type of bacteria usually found in the stomach
Zollinger-Ellison syn
A rare condition that causes the stomach to produce too much acid
Erosive esophagitis (EE)
A condition characterized by inflammation of the lining of the esophagus
Gastric and duodenal ulcers
A raw place or sore in the lining of the stomach or intestine

Proton Pump Inhibitors OTC

Over-the-counter PPIs include Nexium 24HR and Prilosec OTC. These PPIs treat frequent heartburn.

Frequent heartburn is heartburn that happens two or more times a week. PPIs do not provide immediate heartburn relief. They may need several days to begin working.

People should not take OTC proton pump inhibitors for more than two weeks at a time. They should wait at least four months before taking them again.

PPI Off-Label Uses

Taking OTC proton pump inhibitors longer than indicated on their label is an off-label use. The FDA has not approved this. But it acknowledges that doctors may recommend taking OTC proton pump inhibitors for more than 14 days.

“FDA acknowledges that consumers, either on their own, or based on a healthcare professional’s recommendation, may take these products for periods of time that exceed the directions on the OTC label. This is considered an off-label (unapproved) use.”

Source: FDA Safety Announcement, updated Aug. 4, 2017

Prescribing PPIs to infants is another off-label use. PPIs are not approved for babies younger than 1 month of age.

Studies have shown this practice may be ineffective. It is also associated with an increased risk of asthma and allergies. Other studies have linked PPIs to childhood bone fractures.

Dosage Information on Proton Pump Inhibitors

Dosage varies with each PPI and the condition it is being used to treat. A doctor will advise a patient on the dose needed and how often a patient should take a PPI drug. Dosages may start at 15 mg per day. Doctors have prescribed doses up to 240 mg per day.

When Should I Take a PPI?

Patients should ask their doctor when to take a PPI. Generally, doctors tell patients to take PPIs on an empty stomach — about 30 minutes before a meal. Often this will be first thing in the morning. Some patients take a second dose before dinner when a doctor deems it necessary.

PPI Side Effects

Proton pump inhibitor side effects range from minor to life-threatening. The most common side effects include constipation, headache, diarrhea and vomiting. Some of the most serious PPI side effects involve a range of kidney problems. These include kidney failure — also called end stage renal disease (ESRD).

PPI Interactions

Proton pump inhibitors may cause drug interactions with 290 other medicines. Some of these may be minor. But some PPI interactions can be serious or even life-threatening.

People should tell their doctor about all other drugs they are taking before using PPIs. They should ask their doctor whether they should be taking PPI drugs at all.

What Are the Differences Among PPI Drugs?

Studies tend to show that all PPIs are about the same in most cases. But their costs can vary widely.

Some PPIs may be more effective than others at treating certain conditions. And some may present a greater risk for certain side effects.

A 2010 study reviewed research comparing several PPIs.

How Does Nexium Compare to Other PPIs?

Nexium (esomeprazole) is as effective as other PPIs in most treatments. Studies have found it may be better than other PPIs at healing esophagitis at four to eight weeks. This applied only to moderate to severe cases.

How Do Prilosec and Aciphex Compare to Other PPIs?

A study found Prilosec (omeprazole) and Aciphex (rabeprazole) performed better than other PPI drugs at controlling GERD. Prilosec and Aciphex worked better than other PPIs in high doses. Another study found older patients with esophagitis responded better to the Prilosec and Aciphex than they did to other PPIs.

How Does Protonix Compare to Other PPIs?

A 2016 study found Protonix users faced a greater stroke risk than users of other PPIs. Researchers found overall PPI use increased stroke risk by 21 percent. But the risk for Protonix users was highest at 94 percent.

How Does Vimovo Compare to Other PPIs?

Vimovo is unique in that it combines a PPI with a pain reliever. It contains the active ingredients of both Nexium (esomeprazole) and Aleve (naproxen). It is also the most expensive proton pump inhibitor in the U.S. According to CNN, a month’s supply of the prescription drug cost more than $3,000 in early 2018. A month’s supply of the OTC versions of both Nexium and Aleve cost about $36 a month.
